Effect of growth fluid concentration on characteristics of CeO2 nanorods and WO3/CeO2 nanostructured hybrid films for electrochromic applications

In this study, cerium oxide nanorods were synthesized on fluorine-doped tin oxide-coated glass substrate using a hydrothermal process at different growth fluid concentrations varying from 0.01 M to 0.05 M and characterized. A nanostructured WO3/CeO2 hybrid films were formed by depositing tungsten oxide on cerium oxide nanorods by Direct current (DC) magnetron sputtering process at a partial pressure of oxygen (PaO2) 8 x 10(-4) mbar and analyzed its structural, morphological, optical, and electrochemical properties by X-ray diffraction, scanning electron microscope, EDX, and UV spectroscopy techniques. The electrochromic properties were studied by developing a three-electrode electrochemical cell with WO3/CeO2 nanostructured hybrid film as a working electrode and observed improvement in the electrochromic properties of WO3/CeO2 nanostructured hybrid film developed at various growth fluid concentration for growing cerium oxide nanorods.

Automated summary

Cerium oxide nanorods were synthesized on a fluorine-doped tin oxide-coated glass substrate using hydrothermal process, and a nanostructured WO3/CeO2 hybrid film was formed by depositing tungsten oxide on the nanorods. The structural, morphological, optical, and electrochemical properties of the hybrid film were characterized. Improvement in the electrochromic properties of the film was observed with varying growth fluid concentration for growing the cerium oxide nanorods.
